The first sex manuals came from China. Sex manuals are concerned with the best ways to make love, to prolong the sexual act, to have fun, to have children and to maintain good health. These manuals are easy to use and contain precise illustrations. They are intended for beginners, and the advice is aimed at both men and women alike. Women learn to release the energy and power of their ovaries, men the power of their sperm, to circulate these energies consciously in the body. The sexual union symbolises the unity of the earth and the heavens.
It is an interesting subject! I have no answer to you. I have never been with many girls at the same time. But I have been thinking about the subject, some and been reading about it. I have a teacher I visit from time to time from the Indian tantra system.
Taoism is a spiritual tradition that embraces our sexual desire and uses it within our bodies as a force for healing and spiritual growth. Desire is a rich and potent part of our human experience. The Taoists think of desire, called sexual energy or jing chi, as part of our life energy, or chi. To be passionate is to be full of chi. The English words "desire" or "passion" connotes a feeling of yearning and fervor that includes sex, but they also reflect our strongest feelings about life.
